What Song Are You Listening To?

With music being my absolute favorite thing in life, I always find myself curious what people are listening to when I see them with their iPods. Whether it be at the gym, out walking, etc... I always find myself wanting to know what people are listening to. I remember recently I had this super jacked guy at the gym walk past me and he was pumping old school Michael Jackson ("Beat It") in his headphones. Good times.
